Dear Mather Smith,

I am grateful for the time you took to write a reference for me. I now that it took a lot of time and thought to make such a profound letter, and I know that the recruiting manager was impressed by it.

I know that without your letter I would have struggled to rise above other candidates, and so recognize that my success is down to you. If there is anyway that I can help you in the future please do not hesitate to give me a ring. Many thanks again for such a glowing reference.
